I got some nss, ifolder and lum errors when installing OES11. It also looks like mono is not installed, at least the service and ifolder is not working. Due to these issues, i would like to know how to uninstall every piece of OES11 so i can start over with OES11. Can you use yast to uninstall OES11? Maybe remove the add-on and this will unistall OES11?
